Abstract: A controller may receive, from a sensor device, machine velocity data indicating a velocity of a machine controlled by a remote control device. The controller may determine, based on the machine velocity data, a distance to be traveled by the machine until the machine stops traveling after a communication, between the machine and the remote control device, is interrupted. The controller may generate, based on the distance, an overlay to indicate the distance. The controller may provide the overlay, for display, with a video feed of an environment surrounding the machine.
